  "summary": "crypto: atmel-ecc - reject hardware ECDH without a public key",
  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ncrypto: atmel-ecc - reject hardware ECDH without a public key\n\nThe hardware ECDH path in atmel_ecdh_compute_shared_secret() uses the\nprivate key stored in the device. However, the public key is cached only\nafter atmel_ecdh_set_secret() successfully generated that private key\nfor the current tfm.\n\natmel_ecdh_generate_public_key() already rejects requests when no public\nkey is cached. Add the same check to atmel_ecdh_compute_shared_secret()\nto prevent the device from using a private key that was not generated\nfor the current tfm.",
